Knowing places in books

 I am currently reading A Spy Alone, which I am enjoying quite a lot. I started it not expecting much, just a half decent thriller, but it really caught my attention. Anyway, in the very first pages, it mentions and features two cities, Oxford and Reading. The former is more prominent than the latter, and the latter is truly a large town, not a city, but I digress. I have been to both is what I wanted to say. And it is one of the little bit of literary joys I have when I read: that first-hand knowledge of a place you are reading about. Am I the only one who feels like this? What about you?
